Unless, like me, you might have a novel in your pocket....
If I sit there and stare at it long enough, I realize I never have seen a book with quite those proportions.
Octodecimo is the closest format, but very rare.
Sherlock Holmes would notice, that’s for sure (and it’d be just my luck to run into him), and after seeing me and my pocket novel around town for a year or two deduce that nobody, but nobody, could be such a slow reader.
